The quality inspection organization shall keep the circulation records of samples throughout the testing period for verification. If samples need to be retained, safe storage measures shall be taken. 13
5.7 Quality Control of Results
5.7.1 The quality control organization shall have quality control procedures and quality control time to monitor the validity of test and calibration results, which may include (but not limited to) the following: (a) Regular use of certified reference materials (reference materials) for monitoring and/or use of secondary standard materials (reference materials) for internal quality control; (1) Comparison or proficiency testing between participating laboratories; (e) Repeated testing or calibration using the same or different methods; (d) Retesting or recalibrating retained samples; (e) Analyzing the correlation between the results of different characteristics of a sample. 5.7.2 The quality control organization shall analyze the quality control data, and when it is found that the quality control data is about to exceed the predetermined judgment basis: planned measures should be taken to correct the problems and prevent the reporting of erroneous results. 5.8 Result Report
5.8.1 The quality inspection agency shall, in accordance with the relevant technical specifications or standards, require and specify the procedures: timely publish its test and/or calibration data and results, and ensure that the data and results are accurate, objective and authentic. The report shall use legal measurement units. 5.8.2. The quality inspection agency shall uniformly stipulate the format of the test report. The test and/or calibration report shall include at least the following information: (a) Title; (b) Name and address of the quality inspection agency, and the location of the test and/or calibration if it is different from the address of the quality inspection agency; (c) Unique identification of the test and/or calibration report (such as serial number) and each page! (d) the name and address of the customer (where necessary); (e) identification of the label or method used; (f) description and identification of the condition of the samples; (g) the date on which the samples were received and the date on which the tests and/or calibrations were carried out (where necessary); (h) a description of the sampling plan used, if relevant to the validity or application of the results; (i) the results of the tests and/or calibrations; (i) the signature or equivalent of the person who conducted the tests and/or calibrations and of the person who approved the report; (k) a statement, where necessary, that the results relate only to the samples tested and/or calibrated. 5.8.3 Where explanations are required for the test and/or calibration results, the report may also include the following: (a) deviations, additions or omissions from the test and/or calibration methods and information on specific test and/or calibration conditions; (b) a statement of conformity (or nonconformity) to requirements and/or specifications; (c) information on uncertainty when it is relevant to the validity or application of the test and/or calibration results, or when the customer requires it, or when the uncertainty affects the judgement of the conformity of the results; and (d) additional information required by specific methods, customers or customer groups. 5.8.4 For test reports that include sampling, the following information should also be included: (a) Sampling period:
(b) Standards or specifications related to sampling methods or procedures, and deviations, additions or deletions from these specifications:
(c) Sampling locations, including any diagrams, sketches or photos; (d) Samplers;
(c) List the sampling plan used:
(I) Detailed information on environmental conditions that may affect the interpretation of test results during sampling.
5.8.5 If the test report contains subcontracted results, these results should be clearly marked, and the subcontractor should report the results in writing or electronically. 5.8.6 When the test and/or calibration results are transmitted by telephone, telex, fax or other electronic/electromagnetic means, the requirements of this standard should be met. 5.8.7 Substantive changes to an issued report should be made in the form of additional documents or replacement reports, and should include the following statement: "Supplement to the report, serial number (or other identification)", or other equivalent text.
